Prestressed concrete bridges bruilt using the cantilever method
This guide provides a highly detailed description of the design andconstruction of prestressed concrete bridges built by the cantilevermethod.
Highly informative and lavishly illustrated, each of the ten chapterscovers one of the stages in the development of these types ofstructures: preliminary design, detailed design, calculations,preparation of the invitation to tender, construction, monitoring ofworks, maintenance, etc.

Highly informative and lavishly illustrated, each of the ten chapterscovers one of the stages in the development of these types ofstructures: preliminary design, detailed design, calculations,preparation of the invitation to tender, construction, monitoring ofworks, maintenance, etc.
Thanks to its comprehensive coverage of the subject, this guide willbe of interest to anyone involved in the design and construction ofbridges built by the cantilever method (project managers, consultingengineers or technicians, construction managers, works inspectors andarchitects) in addition to teachers specialising in civil engineering.
This technical guide is intended for engineers and architects involvedin designing, calculating and verifying concrete bridges built by thecantilever method.
